Thanks Madmax. Looks like I'll wait till aftermarket gears are avaliable before I do this guy's gun. Besides I really don't have the time.
Nice to see that the mechanical 3Round burst shouldn't ware out any faster with any spring upgrade. That was my main concern from TM since we all know what monkey metal they use. I still don't think their copying of rounding the corners would solve the famous mechbox cracking problem. Beefed up the top by filling the usual hollow space, but not the bottom. Took them long enough to do something about it. I hope they know that putting more metal around the spur gear doesn't make it a reinforced mechbox. They should save the extra monkey metal money for just better metal.
